Obrien is gonna KTFO the Martian Manhunter, much to my disappointment....
Lesnar will GnP Mir with baby hammer fists while laying on him and get a stoppage...
GSP will eat a few kicks in the first round then run a merciless ground clinic for the next two before winning via GnP late in the 3rd or early in the 4th.
Other than that Danzig, Hendo, Dolloway FTW.

The Bonner and Fitch fights are the two I'm thinking will be the most entertaining though.

The unfortunate thing here is most people don't know as much about him as they think. Jake finished every fight he had up until his second UFC fight. After beating Herring he got KO'd by a solid striker in Arlovski and a beast in Velasquez. That made him realize he was too small for HW. So, for the first time in his life, he cuts weight and gasses HARD because of it. Rewatch O'brien v Wellisch in rd 1 before he gasses. He look great on his feet. Jake has really good boxing, and his GnP is awesome. The problem is no body knows anything of his fights pre Herring so they don't know this.

Jake is ready for this fight. He's bigger and stronger than Jones. He'll have better hands, and comparable if not better wrestler. I think a lot of people will be surprised in this fight. But hey, if I'm wrong, I'm wrong.
